Dfu problem in segger

[suvarna_kadam]

Hi

Getting problem in DFU feature while using segger embedded studio.Device gets programmed  successfully but stops working after that.

I am following the same process for keil and segger IDE. For keil it's working fine, but for segger it fails.

For DFU I am following this thread :

devzone.nordicsemi.com/.../

I am using sdk 11

Has any one tried dfu feature using segger IDE?

Are there any additional steps for DFU in segger IDE?

Hi.

1) I recommend that you use SDK 12.3, that is the latest SDK compatible with nRF51, it also has the same SoftDevice as SDK 11.

2) If you wish to use Segger Embedded Studio, you have to import the Keil project to Segger Embedded Studio, take a look at this guide.

3) Take a look at the Infocenter where the DFU bootloader is explained, and follow that procedure under testing.

Best regards,

Andreas

Hello Andreas, Thanks for the reply.

1) I have tried the example project ble_app_uart, ble_app_hrs and experimental_ble_buttonless_dfu on SDK 12.3 (with softdevice 130).

1.a) ble_app_uart worked successfully in Segger IDE, ble_app_hrs  gets stuck when you do the debugging. Please see the image below.

)

Note: I had to use the debug mode for ble_app_hrs, because it was not even advertising in normal mode.

1.b) In the application experimental_ble_buttonless_dfu, I am getting a compilation error. Attaching the error trace below.

2) We have already done the porting of projects from Keil to Segger already  and made everything work except DFU in SDK 11 (Softdevice S130 and nrf51-dk)

3) We have been using DFU successfully in SDK 11 (in Keil) for quite some time on nrf51-DK and our product version with nrf51822.

4) Our work is almost complete on SDK 11 except for DFU (for our product) in Segger. Is there anyway you can guide us to use SDK 11 itself for DFU applications itself Segger. The reason is that it will take good amount of time to port all our applications to SDK12 from SDK11.

Thanks a lot for your time :)

I had used XML file, got  following error

"cannot find run section .fast_run referenced in fast"

Hi.

Can you try the project vibe made?

Best regards,

Andreas

[suvarna_kadam]

Hi

Sorry,I an not aware about vibe mode.

[AndreasF]

Hi.

I'm not talking about vibe mode, sorry for the confusion. I was talking about the reply the user Vidar Berg made, he attached a project that is ported to Segger Embedded Studio.

Vidar Berg said:

suvarna_kadam, I've ported the project to Segger embedded Studio. Download the attached zip and copy the extracted folder to \nRF5_SDK_11.0.0_89a8197\examples\dfu before you run the project. I have verified that it runs on a 51 DK (let me know if you're targeting a different Chip variant), but have not tested the DFU part. 

bootloader_ses.zip

Note that you need to place the non_init section in the same RAM area in both app and bootloader if you intend to support buttonless DFU, see section placement file. This area is uses to exchange data between bootloader and app. 

 This reply.

Best regards,

Hi Vidar,

Thank you.

I am able to compile (DFU boot-loader project) without error using the project folder you have provided with nrf51 DK.

We are working with nrf51822 chip. Do you recommend any changes in the project you have shared for this chip?
